Abstract: (IOP)
The GUTs in curved space-time with torsion are considered. (These GUTs are finite in flat space-time.) The question of the behaviour of effective coupling constants corresponding to the parameters of nonminimal coupling of matter with an external gravitational field is investigated. It is shown that in a strong gravitational field these effective coupling constants tend to conformal values or increase in an exponential way.- GRAND UNIFIED THEORY: FINITE
